What category of disinfectant is dimethyl benzyl ammonium chloride?

This is the main ingredient in many lysol products and I am doing a project on it but can't for the life of me find out what it actually does to kill the bacteria. I Wikipediaed disinfectants and think it might be a quaternary ammonium compound. I'd really like to know for sure though. Any help with this or sources with more about the compound would be appreciated!
